The ULC Monitor is a simple tool to monitor the communication between the UI Engine and connected applications. It can be started when invoking the UI Engine with the -m option.

On the left it shows the currently connected applications. On the right it lists communication statistics:

• Sent Requests: the number of requests from the UI Engine to the application.
• Sent Events: the number of events sent from the UI Engine to the application.
• Received Requests: the number of received requests from applications.
• Sent Bytes: the total number of bytes sent from the UI to the applications.
• Received Bytes: the total number of bytes sent from the applications to the UI.
• Average Send Size: the average message size for all messages sent from the UI to the application.
• Average Received Size: the average message size for all messages received by the UI from the application.

The functions of the buttons are:

• Logging On/Off: toggles whether the transmitted data should be logged to the currently configured Log file. The Log file name can be configured by starting the UI with the parameter -logfilename . The default log file name is ulcui.log and will be written to the UIEngine\bin directory.
• Reset: resets the counters.
• Stop UI: stops the UI Engine.

In addition a popup menu over the connection list allows a selected connection to be terminated and a popup menu over the communication section allows the current statistics to be copied to the clipboard.
